Problems solved by technology

[0004] In order to solve the technical problems of non-standard insulating gaps and post-filling insulating gaps in high-temperature and high-pressure environments, which require the use of lightweight insulating materials and post-filling processes, this application provides a production method for insulating bamboo balls, which is made of mature moso bamboo felled in winter Insulated bamboo balls, after fermentation, high-temperature cooking and high-temperature baking, thoroughly kill insect eggs and microorganisms that may exist in the bamboo balls, and dip-coat high-temperature-resistant insulating paint to strengthen the insulation function of bamboo balls. After filling, they have good fluidity and are easy to Full of various irregular non-standard gaps, high temperature and high pressure resistance, not easy to carbonization, light weight, corrosion resistance, high strength, impact resistance, is an ideal filling material for insulation, can be used in aerospace equipment and long-term fatigue operation Large mechanical equipment

Embodiment 1

[0018] A kind of production method of insulating bamboo ball, comprises the following steps:

[0019] (1) Initial processing of moso bamboo: select mature moso bamboos cut in winter with a bamboo age of more than 2 years, split them into bamboo slices, and select bamboo slices whose thickness exceeds one-third of the diameter of the bamboo ball to dry or sun-dry;

[0020] (2) Ball blank production: Use a ball digging machine to dig out bamboo ball blanks with a diameter of 5 mm along the green strips of the bamboo slices. The shape is required to be complete and the size is uniform;

[0021] (3) Ball blank fermentation: put the excavated bamboo pellets into an aqueous solution containing mixed strains of Bacillus subtilis and lactic acid bacteria to ferment for 7-10 days, take them out, wash and drain; the mixed strains of Bacillus subtilis and The weight ratio of lactic acid bacteria is 1:5; using mixed strains for fermentation can first activate each strain, cultivate a mixe...

Abstract

The invention relates to the technical field of forest product processing, in particular to a production method of insulating bamboo balls, which uses mature moso bamboo as a raw material, and undergoes primary processing, billet production, fermentation, high-temperature cooking, drying, insulating varnish, and secondary baking. Drying, ball blank grinding, secondary painting, hot air vibration drying and other steps to eliminate insect eggs and microorganisms in the bamboo balls, impregnated with high temperature resistant insulating paint, strengthen the insulation function of the bamboo balls, and the made insulating bamboo balls have good fluidity when filled. , easy to fill various irregular non-standard gaps, high temperature and high pressure resistance, not easy to carbonize, light weight, corrosion resistance, high strength, impact resistance, is an ideal filling material for insulation, can be used in aerospace fields and long-term fatigue Large machinery in operation.

Description

technical field [0001] The invention relates to the technical field of forest product processing, in particular to a production method of insulating bamboo balls. Background technique [0002] my country's moso bamboo resources are very rich, especially in poor mountainous areas. The huge moso bamboo resources rely on manual felling and are difficult to effectively use due to traffic conditions. Moso bamboo has the advantages of light weight, solidity, good insulation performance, high temperature resistance, corrosion resistance, and easy degradation. It is a high-quality raw material for building materials, handicrafts and many daily necessities. At present, the development and utilization of moso bamboo is basically limited to this, and its good insulation performance has not yet been developed and utilized. [0003] At present, the insulating materials used in high-temperature and high-pressure environments are usually inorganic non-metallic materials such as ceramics, ...
